In Limbo's building, a human rights advocate named Ari was off to her usual trouble-making mischief. To apes, humans weren't good for much other than to be used as pets or simple house servants. He earned profit on volume selling, as his human specimens smelled like humans and weren't considered luxury items to apes.
In the city, Leo met Limbo, an orangutan who traded humans for money. After the lot was rounded up they were tossed into cages and hauled back to the Ape City, where they were sold off as slaves. With gorillas on horseback and chimpanzees running on all fours, the apes chased after humanity - the inferior race they had mastered and now hunt. After a short contemplation Leo took off with them and ran. Shortly after crashing Leo looked around to see rustling among the brush. Crashing in a jungle, his crew-mates on-board the Oberon searched for him in vain. Leo lost contact with his space station and was pushed forward in time to 5021 and a strange new world.
Astronaut Leo however had other ideas and snuck aboard another escape pod and travelled in pursuit of his chimp trainee into space. When the chimp was lost, the commander wrote-off the chimp and prepared to forget the storm. Leo's Spacepod Crashes Towards The Alien Planet The Oberon's commander decided to send out a chimp - Pericles - to see if conditions were safe to send out human pilots to explore the storm. The storm sent all of the radio and television broadcasts of Earth out toward the Oberon. Leo was summoned to the command deck of the space station where a new situation had emerged a giant electromagnetic storm.
Pericles learned from training simulators and was rewarded with treats when he achieved his objectives. Onboard the Oberon space station, an astronaut named Leo Davidson worked closely with chimpanzees and orangutans who were trained to serve as 'guinea-pigs' for particularly dangerous exploration missions in space.
